IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No.144,755, dated November18, 1873; application filed April 16, 1873.

To all whom it may concern:

Be it known that I, J OIIN I. FRIEST, of Chillicothe, Missouri, haveinvented certain new and useful Improvements in Ghurns, of which thefollowing is a specification, reference bein g had to the accompanyingdrawings.

The invention relates to providing a churnbarrel with a vertical hangingdasher, provided with adjustable paddles, and suspended in the barrel byan open frame having journal-slots, the upper end of the dasher having ahead or button to sustain it, while that part which operates in theaperture in the frame is provided with a grooved pulley-wheel, connectedby a band with a bandwheel at the end of two arms hinged to the frame.The object of the invention is to provide an adjustable frame anddasher, such as may he used upon vessels of different forms, for thepurpose of churning butter.

Figure l is a vertical section through the line :v w of a deviceembodying the elements of the invention. Fig. 2 is a plan view of thesame.

A in the accompanying drawings is a churnbarrel, provided with theremovable covers 13, on top of which, at their centers, is thecoincident arch a, between which passes the shaft D, the lower part ofwhich is suspended in the barrel A by the button E, which comes incontact with the upper sin-face of the hollow frame F, provided, on itsupper and under parts, with the journ al-slot-s b I), through which theupper part of the shaft D is admitted to its bearings, that part of theshaft which passes through the aperture a in the frame F being providedat its (enter with the pulley-wheel H. The shaft D, below the under sideof the frame F, is enlarged, and provided with a shoulder,

which impinges upon the under side of the frame F, and prevents theshaft being elevated too much. The portion of the shaft 1) which entersthe barrel A is furnished with apertures c, in which are placed the endsof the armsf of the paddles I, the angles of which are adjustable in theapertures f, to force the cream up or down. The frame F is provided witha recess. The vertical lips g of the frame F fit over the upper parts ofthe outer surface of the barrel A, and by means of the set-screws L areclamped thereon. Upon the side of the frame opposite the set-screw L arejointed to the frame, by the pivot h, the ends of the arms M, whichextend parallel to each other a proper distance, their other extremitiesbeing provided with the shaft N, operated by the crank I and rigidlysecured upon the shaft N is the band-wheel It, connected by the bandiwith the pulley-wheel II.

One of the covers B being removed, the material to be churned is placedin the barrel A, and the operation is performed by simply rotating thecrank 1 which operates the dashershaft D, causing the paddles I torevolve, and affect the material in the barrel.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

The adjustable and detachable frame F, provided with the journal-slots1), arms M, setscrew L, band-wheel R, and band "i, in combination withthe pulley H on the shaft D, provided with the paddles I, substantiallyas shown and described.
